Foil baked pollack and asparagus with couscous

This is a healthy, low fat meal that can be made with any sustainable firm white fish such as pollack, cod, haddock or even salmon. It also makes the most of this season's superstar veg – asparagus.

I've kept things really simple and the ingredients to a minimum. If you want to jazz it up a bit you can cook some sliced Mediterranean-style vegetables such as red onion, peppers and courgettes in foil parcels next to the fish parcels on the barbecue, and mix them through the couscous before serving.
